Embodiment 1

[0059] Please refer to figure 1 , is a flow chart of a welding process provided in Embodiment 1 of the present application, and the welding process includes:

[0060] S101: Welding the first part of the flexible connector into the connection via hole of the horizontal printed board;

[0061] S102: Bending a second part of the flexible connector except the first part to obtain a bent part;

[0062] S103: Solder the upper end of the bent portion on the pad of the vertical printed board, wherein the length of the bent portion is greater than the distance between the connection via hole and the pad.

[0063] In the specific implementation process, the welding process can be specifically applied to the production of circuit boards in notebook computers or smart phones, and can also be applied to other electronic devices with printed boards in an orthogonal position relationship, such as Figure 2A and Figure 2B As shown, here, examples are not given one by one.

Abstract

The invention discloses a welding technology and a structural component. The welding technology comprises the steps that a first portion of a flexible connecting piece is welded to a connection via hole of a horizontal printed board; a second portion except for the first portion of the flexible connecting piece is bent, and a bent portion is obtained; the upper end of the bent portion is welded to a bonding pad of a perpendicular printed board, wherein the length of the bent portion is larger than the distance between the connection via hole and the bonding pad. The technical problem that a circuit board is likely to break due to external stress of electronic equipment in the prior art is solved, and the technical effect of lowering mechanical stress of a welding point is achieved.

Description

technical field [0001] The invention relates to the field of electronic product manufacturing, in particular to a welding process and structural parts. Background technique [0002] With the deterioration of the environment and the continuous improvement of product quality requirements, electronic products must undergo environmental tests such as vibration and temperature cycles after assembly. The mechanical stress and temperature stress brought about by the test process will cause certain deformations to the structural parts of the product. The deformation of the structural parts indirectly leads to a large mechanical stress between the vertical printed board and the horizontal printed board. [0003] In the prior art, the connection method of vertical printed board solder joints is generally to weld rigid silver-plated copper wires at the joints. The appearance of solder joints is required to be bright and burr-free. The welding method is as follows: figure 1 shown. In ...
